ABSTRAK

Internet of Thing (IoT) adalah sebuah konsep dimana suatu objek yang memiliki kemampuan untuk mentransfer data melalui jaringan tanpa memerlukan interaksi manusia ke manusia atau manusia ke komputer.

Pada penelitian kali ini penerapan internet of things digunakan dalam merancang sistem kontrol pakan ikan dan kekeruhan air serta moinitoring kualitas air. Beberapa komponen yang digunakan meliputi arduino mega, node mcu,sensor jarak,suhu,Ph,kekeruhan,servo,solenoid valve,waterpump dan website untuk interfacenya.

Hasil dari penelitian yaitu kontrol pakan dilakukan dengan melakukan setting waktu pemberian pakan dan durasi waktu pumbukaan servo yang dilakukan pada website.Kontrol kekeruhan air terjadi ketika sensor kekeruhan mendekteksi nilai 25 NTU kemudian sistem membuka solenoid valve untuk melakukan pengurasan air sampai nilai ketinggian air 10% dan mengaktifkan waterpump untuk mengisi air kembali sampai nilai ketinggian air sebesar 90%

ABSTRACT Internet of Thing (IoT) is a concept where an object has the ability to

transfer data over a network without requiring human to human or human interaction to a computer. In this study the application of the internet of things was used in designing fish feed control systems and turbidity of water and monitoring water

quality. Some components used include Arduino Mega, NodeMCU, ultrasonic sensor, temperature, pH, turbidity, servo, solenoid valve, waterpump and website for interfaces

The results of the study are feed control by setting the feeding time and the servo surface duration of the website. The turbidity control occurs when the turbidity sensor detects the value of 25 NTU then the system opens the solenoid valve to drain the water until the water level is 10% and enable waterpump to fill the water again until the water level is 90%
